Choice of Monitor Calibration hardware/software

[D Fosse]

Afterthought: Is it a U2713H or a U2713HM? One is wide gamut, the other standard. But the U2410 is wide.

One standard and one wide would certainly be inconsistent - until they're both profiled and viewed in a fully color managed environment. Then they'll be identical and correct, except that the 2410 will be able to display some very saturated colors that the other can't.

Some of the old Spyders used to be only allowed for a fixed number of monitors or computers.  X-rite used to be too, but they did away with it.  I don't know if Spyder still has that gear-number restriction which might be an issue if you change equipment.  When I had my second Spyder, it required some online registration to get the updated software to even work on a brand new install (Check for "newer version" which it then locked up.).  It took almost a week for them to give me a working registration number for it to even work.
